Yohoho! Puzzle Pirates is a massively multiplayer online game developed by Three Rings Design, a company acquired by Sega Sammy Holdings in 2011. The player takes the role of a pirate, adventuring on the high seas and pillaging money ("pieces of eight") from roaming enemy ships (human or computer-controlled). The mechanics of Puzzle Pirates are driven by puzzles. For example, to effectively sail a ship, players must play puzzle games representing work at the sails for speed, pumping bilge water to remove it from the ship, and carpentry to fix any damage the ship may take.
